Question

the forward voltage drop of an led is​

Answer 1

Explanation:

Typically, the forward voltage of an LED is between 1.8 and 3.3 volts. It varies by the color of the LED. A red LED typically drops around 1.7 to 2.0 volts, but since both voltage drop and light frequency increase with band gap, a blue LED may drop around 3 to 3.3 volts.

Answer 2

The Forward voltage drop of an LED:

• If the voltage at the anode is more positive than the voltage at the cathode (if you connect + to the anode), the voltage drop across the diode (LEDs) is the forward voltage.
• It isn't a predetermined number.
• An LED has a forward voltage of 1.8 to 3.3 volts.
• The colour of the LED has an impact.
• A red LED normally drops 1.8 volts, but when the bandgap narrows, both the voltage drop and the light frequency rise; a blue LED may drop 3 to 3.3 volts.
